The local factors behind roof inspection in Kawartha Lakes
Two houses on the same Kawartha Lakes street, built the same year, can need completely different roof inspection work — and usually do.
Wind loading off Lake Ontario pushes driving rain against the south and west faces of a house, which is why water entry so often shows up on one side of a Kawartha Lakes home and nowhere else.
Post-war subdivisions across Durham share the same construction generation, so when one street starts showing the same defect, the neighbours usually follow within a couple of seasons.
Across Bobcaygeon, Woodville, Fenelon Falls, Kirkfield and Omemee, the housing stock changes street by street, and the correct method changes with it. A century home with a soft-brick stack does not get the same treatment as a 2010 build with a factory-built vent — using one method on both is how systems get damaged.
the practical takeaway is that a roof inspection visit should start with an assessment, not a tool. Any crew that begins work before telling you what they found is guessing on your behalf.
